My site changes frequently(daily). after checking i found that apache has ExpiresDefault A2419200 which spells to 28days. I changed it to ExpiresDefault A0 and reload Apache. Some end-users are now seeing the new content but some are still seeing the old pages. What else i missed?If someone already has a cached version with the 28-day expiry, their web browser (or an intermediate proxy) is likely to keep using it until it expires or until they force a reload. Nothing you do to your web server can force those existing copies to expire prematurely.
hi Jake,try adding those meta tags to your (x)html files (into the head part of course):
<meta http-equiv="expires" content="-1"> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache">this won't force your clients to reload the page, but it should suppress future caching. it's just html, so sure not every browser will interpret that.
